Description

Technical Field

[0001] This utility model relates to the field of handle structure technology, specifically to a box handle structure. Background Technology

[0002] In the logistics, transportation and warehousing sector, cardboard boxes are widely used due to their advantages such as low cost and easy recycling.

[0003] To facilitate handling, many heavy or frequently moved cardboard boxes are equipped with handles. However, existing cardboard box handles are mostly plastic handles directly glued to the outside of the box or simple rope perforation structures, which have obvious drawbacks:

[0004] First, external handles are easily knocked off during transportation, and since they are only bonded to the smooth surface of the carton by adhesive, their load-bearing capacity is limited and their reliability is poor.

[0005] Secondly, many handles are single-function and lack an emergency carrying solution when there is no handle, making them inconvenient to use;

[0006] Furthermore, the installation process for some complex handles is cumbersome, requiring specialized tools or significant modifications to the cardboard box, which affects the box's strength and sealing performance.

[0007] Therefore, there is an urgent need for a carton handle that is securely installed, has strong load-bearing capacity, has dual usage modes, and is easy to assemble and disassemble. To address this, we propose a carton handle structure to solve the aforementioned problems. Utility Model Content

[0008] Technical problems to be solved

[0009] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a box handle structure that can solve the technical problems of poor reliability and limited functionality of carton in the existing technology.

[0012] This utility model provides a box handle structure, including a first fixing part and a second fixing part respectively disposed on the inner and outer sides of the box, the first fixing part and the second fixing part being detachably disposed to jointly clamp and fix to the side wall of the carton; it also includes a handle component, the handle component being detachably installed on the first fixing part and / or the second fixing part.

[0013] Furthermore, the first fixing part includes a fixing frame that passes through the opening in the side wall of the carton, and the second fixing part includes a cavity that accommodates the fixing frame, wherein the fixing frame is engaged and fixed with the cavity.

[0014] Furthermore, the fixed frame and the chamber are fixed together by a flange structure, the flange structure including a first flange disposed on the outer wall of the fixed frame and a second flange disposed on the inner wall of the chamber, the first flange and the second flange being misaligned and engaged.

[0015] Furthermore, the outer end face of the fixed frame is provided with a mesh structure to enhance its structural strength.

[0016] Furthermore, the handle component is detachably connected to the fixing frame via fasteners.

[0017] Furthermore, the fastener is a screw, and the fixing frame has a plurality of screw holes for the fastener to be locked in.

[0018] Furthermore, the screw holes are arranged in a manner that is not parallel to the side of the carton.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example:

[0040] Please refer to the appendix. Figure 1-6 This solution proposes a handle structure for installation on the box 1, especially on the carton. The core of this structure is a fixed base consisting of inner and outer parts, and a special handle that can be flexibly installed and removed.

[0041] The entire structure mainly includes a first fixing part 10, a second fixing part 20, and a handle component 30.

[0042] The first fixing part 10 is located on the inner side of the housing 1, and the second fixing part 20 is located on the outer side of the housing 1. The two are connected to each other in a detachable manner, firmly clamping the side wall of the housing in the middle, thereby forming a stable installation base. The fixing method of the first fixing part 10 and the second fixing part 20 is not specifically limited here, and can be any feasible detachable connection form such as snap, thread, magnetic attraction, etc.

[0043] In a preferred embodiment, the first fixing part 10 includes an outwardly protruding fixing frame 101. The area of ​​the first fixing part 10 is larger than the area of ​​the opening 11. The fixing frame 101 passes through the pre-opened opening 11 on the side wall of the box body 1.

[0044] Correspondingly, the second fixing part 20 is provided with a chamber 201 that matches the shape of the fixing frame 101.

[0045] Optionally, the area of ​​the chamber 201 is slightly larger than the area of ​​the fixing frame 101. During installation, the chamber 201 is aligned and fitted onto the fixing frame 101 to achieve the initial positioning and connection of the first fixing part 10 and the second fixing part 20.

[0046] To enhance the strength and reliability of the connection, such as Figure 2 As shown, one or more first flanges 102 are provided on the outer wall of the fixed frame 101, and one or more second flanges 202 are correspondingly provided on the inner wall of the chamber 201.

[0047] In this embodiment, there are two of each of the first flange 102 and the second flange 202. When the cavity 201 is fitted into the fixing frame 101, the first flange 102 and the second flange 202 are misaligned and pass over each other to form a tight locking. This flange interlocking structure can effectively prevent the two parts from easily separating under the action of external force, thus ensuring the stability of clamping.

[0048] In order to improve the load-bearing capacity of the entire structure, especially when dealing with heavy objects, the first fixing part 10 was reinforced and a grid structure 103 was set on the outward protruding outer end face of the fixing frame 101.

[0049] The grid structure 103 can be a uniformly distributed grid or other reinforcing ribs, which can greatly enhance the rigidity and deformation resistance of the end face of the fixed frame 101, and prevent the fixed frame 101 from collapsing or breaking due to stress concentration when lifting heavy objects.

[0050] Another key aspect of this embodiment is the detachable installation of the handle component 30. The handle component 30 is not permanently fixed, but can be flexibly installed onto or removed from the fixed base as needed.

[0051] Specifically, such as Figure 3 As shown, the connection is made by fasteners 40. The selection of fasteners 40 is not specifically limited. In this embodiment, screws are used as fasteners 40, and several screw holes 15 for screws to be screwed into are pre-set on the fixing frame 101.

[0052] When installing the handle, simply align the handle component 30 with the position, then pass the screw through the corresponding holes on the handle component 30 and the second fixing part 20, and finally screw it into the screw hole 15 of the fixing frame 101.

[0053] Furthermore, the arrangement of these screw holes 15 has been optimized. Instead of being simply arranged parallel to the sides of the carton, they are arranged in a non-parallel manner, such as in an isosceles trapezoidal distribution. This arrangement helps to distribute the load generated when the handle is pulled more evenly across the entire fixing frame 101, avoiding stress concentration and further improving the durability and safety of the structure.

[0054] To ensure ease of use and flexibility, this design also provides a manual lifting function without relying on a dedicated handle. For example... Figure 4 As shown, a handle hole 12 is provided at the center of both the first fixing part 10 and the second fixing part 20.

[0055] The handle hole 12 is a rectangle with semi-circular ends. This is ergonomic, making it easy for fingers to insert and exert force, and avoids stress concentration that may be caused by sharp corners. This allows users to move the box directly through the handle hole 12 without installing the bulky handle part 30 when there is no need for frequent lifting or when the load is light. This enables free switching between "easy mode" and "enhanced mode".

[0056] Finally, as Figure 5 As shown, the handle component 30 itself is also carefully designed. It includes a fixed panel 31 for connection to the fixed base, and a handle 32 for the user to grip.

[0057] The handle 32 is connected to the fixed panel 31 by a hinge (such as a pivot hinge), allowing the handle 32 to rotate or fold relative to the fixed panel 31. This design allows the handle 32 to be folded up when the handle is not needed, reducing space occupation and facilitating storage and transportation.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
